Title: Torque transmitting apparatus.
IPC: F16D11/10
Filed: 1979-05-23
Abstract: Torque transmitting apparatus (10) including a shiftable sleeve member (12) having locking and guiding splines (26a and b) for coupling a first toothed member (14) having external teeth (34) to either one of a pair of toothed members (16), having external teeth (20), and spaced on axially opposite sides thereof. Each locking spline (26a) has working faces (40) whose ends include recesses (38) for axially holding the sleeve member during the transmission of torque to prevent undesirable disengagement during the transmission of torque. The recesses at each end of each locking spline (26a) are spaced from each other with substantially the same minimum chordal relationship as the end of each of the other locking splines. Each guiding spline (26b) has working faces (44) which are spaced so that the chordal thickness therebetween is substantially equal to or less than the corresponding minimum chordal thickness between the recesses at the ends of each locking spline. When the sleeve member (12) is shifted on the first toothed member (14) into engagement with one of the toothed members (16), the relationship between the locking and guiding splines is such that the guiding splines serve to maintain proper axial alignment between the three members (12, 14, 16) and the locking splines serve to prevent undesirable axial disengagement of the locking spline 26a of sleeve member (12) from the teeth (20) of the toothed member (16) during torque transmission. The guiding splines (26b) also cooperate with the teeth (34) of member (14) while disengaging the locking teeth (26a) from the teeth (20) of member (16) to axially guide the sleeve member (12) in the opposite direction. In one preferred embodiment, the locking and guiding splines are arranged in an alternating relationship with each other. Another preferred embodiment has three guiding splines preferably equally circumferentially spaced with respect to each other about the sleeve member.

Title: Electro-magnetic devices
IPC: H01F7/17
Filed: 1979-08-03
Abstract: An electro-magnetic actuator includes a pair of magnetizable members, the one member being hollow and surrounding the other member.

Patent ES-8104562-A1 (ES)
Title: Measurement of residual stresses by local melting
IPC: G01L1/22
Filed: 1980-05-08
Abstract: Residual stress measurements are made using a strain gage and stress relief achieved by local melting of a region of the object being tested by a laser beam or other focused heat source. Surface strain is measured after the molten region resolidifies, and the effect of thermal stress and recast stress is eliminated by subtracting a calibration measurement of an annealed specimen. The method is semi-nondestructive, less costly than existing techniques, and can be used to measure residual stress on the interior surface of pipes.

Patent ES-8401592-A1 (ES)
Title: Air-sealed oil deflector
IPC: F01D11/04
Filed: 1982-03-30
Abstract: An air-sealed oil deflector is disclosed which prevents leakage of oil from bearings of a rotating shaft and which prevents the ingestion of unfiltered atmospheric air which can lead to contaminant build-up and damage to the shaft. The air-sealed deflector includes an annular plenum surrounding the shaft and an annular feed slot interposed between the shaft and the plenum to fluidly interconnect the plenum with the chamber between at least two seal rings immediately adjacent the shaft. The plenum is adapted to receive a continuous flow of forced air from an air supply system including an air prime mover and means for filtering air drawn from the atmosphere which serves as the ultimate air source. The plenum being relatively large in volume, and having a cross-sectional area large with respect to the air feed conduit to the plenum, provides a very uniform source for air flow radially inward, in a sheet-like fashion, toward the shaft through the feed slot. The air-seal is formed as the sheet-like flow of air is released between working clearances between the shaft and the seal rings. A perforated diffuser ring mounted in the feed slot contributes to the desired pressure distribution and eliminates detrimental viscous drag effects.
